Previously, Apple’s apps were only updated when the company issued an iOS update. That slowed Apple’s ability to add new features, fix bugs, address security issues, or make other changes. This has been a massive headache for Apple’s internal development teams.

However, not all of Apple’s apps have been subject to this limitation. The company already made many of its apps available as standalone downloads, including iTunes U, iMovie, the Apple Store app, and those in the iWork suite (Pages, Keynote, Numbers.)

By making these apps available in the App Store, Apple could begin to release updates to the apps at a faster pace, if it chose to do so. However, we understand from sources familiar with the matter that the main reason Apple decided to unbundle apps is so users could delete apps from their devices. Apple at this time doesn’t have plans to update its apps at a faster pace.

Apple quietly published these apps to its iTunes website on Monday. Product Hunt spotted the Mail app in iTunes thanks to a tweet from Owen Williams, leading to speculation that Apple’s other apps will be made available through the App Store, as well.

Note: This article was updated with more information as it became available. Originally we stated that the apps being available in iTunes could lead to a faster release schedule. Why that’s now technically possible, we understand Apple doesn’t currently to intend to speed up the update schedule. We also were able to test app removal on the iOS 10 beta, and updated to note which apps could now be removed.
